In this paper, we propose a discrete wavelet transform based radar pulse deinterleaving methodology using a novel parameter, i.e., the radar antenna scan pattern. Deinterleaving is an important task in electronic warfare, where a passive receiver is used to silently observe the electromagnetic emissions present in the environment. The accuracy and reliability of deinterleaving algorithm determines the success of subsequent operations and enhance the decision making process. Deinterleaving becomes a challenging task where multiple parameter agile radars are operating at different frequency bands simultaneously. We propose a low complexity algorithm based on Wavelet Transform which can accurately deinterleave the radar pulses from the information captured through a single sensor. Depending upon the deinterleaved scan pattern information, a preliminary assessment of the number of emitters and their threat levels can be done.

基于离散小波变换的雷达脉冲解交织方法

在本文中，我们提出了一种基于离散小波变换的雷达脉冲解交织方法，该方法使用了一个新颖的参数，即雷达天线扫描方向图。去交织是电子战中的一项重要任务，在电子战中，无源接收器用于静默观察环境中存在的电磁辐射。解交织算法的准确性和可靠性决定了后续操作的成功程度，并增强了决策过程。当多参数捷变雷达同时在不同频段工作时，去交织成为一项艰巨的任务。我们提出了一种基于小波变换的低复杂度算法，该算法可以从单个传感器捕获的信息中准确地解交雷达脉冲。根据解交织的扫描模式信息，
